摘要： A video signal compression apparatus extracts a specific value written in a read only memory at every system clock pulse. The specific value can be varied at every clock pulse. Therefore, for example, only the center part of a picture can be horizontally compressed. A FIFO memory may be used. It is possible to select a mode with a fixed compression ratio or a mode in which a compression ratio varies at every clock pulse. Further, the fixed compression ratio can be set from the outside. Display position of the picture can also be changed.

摘要： A video signal processing apparatus processes plural kinds of video signals and is used for displaying each one of the processed outputs of the plural kinds of video signals on the same screen. In the video signal processing apparatus, a memory used for a subtitle processing circuit and a memory used for a helper signal separation circuit are used in common by providing a switching means to switch according to an input video signal. A subtitle processing circuit magnifies a video signal with a letter box format such that a horizontally long picture is inserted in a picture with a 4:3 aspect ratio on a horizontally long screen with 2:1 or 16:9 aspect ratio. The helper signal separation circuit is used for receiving a television signal such as an EDTV 2 system which has a helper signal to improve picture quality.

摘要： An organic electroluminescence display includes pixels in a matrix that each emits visible light. A data line driver supplies a video signal to each pixel. The video signal includes first and second frames corresponding to first-eye and second-eye image information. A scanning line driver distributes a scanning signal to each pixel for controlling a supply of the video signal. The display includes an emitter in an arrangement position of the pixels in the matrix. The emitter emits infrared light in a same direction as the visible light. The scanning line driver supplies a control signal to the emitter that indicates a switching timing between the first frame and the second frame, and causes the emitter to emit the infrared light based on the control signal for reception by eye glasses for controlling opening and closing of electronic shutters.

摘要： A gradation correcting apparatus, which can be effectively incorporated into various video devices, enables the display of a sub-display within the domain of main-display (i.e. Picture in Picture) and also enables automatic adjustment of each gradation of the display dependent on the characteristics of the respective input signal. By using both a window pulse and a main- and sub-display switching signal, gradation corrections of the displays are carried out such that either no gradation correction is applied to the sub-display or a proper correction is applied according only to the sub-display signal. In this apparatus, the luminance information related to the sub-display and the luminance information related to the main-display excluding that of the sub-display are independently inputted into a signal correction system, thereby allowing individual processing of this information. Moreover, since the signal delay caused by the arithmetic processing can be precisely compensated for by a delay device, the gradation corrections for the main- and sub-displays are exactly executed according to the respective luminance level information, thus realizing an easy-to-see Picture in a Picture.
